SAP FTP CONNECTION

Hello,

I am writing this blog post for the FTP connection to the SAP ABAP system. While I was configuring the SAP FTP, I haven’t found complete information in a single blog post, So I am writing this blog post.

PRE-REQUISITES:

• FTP credentials.
• SAP GUI credentials with authorization.
• SAP OS access to check IP ports accessibility.
• Network basic understanding.

STEP TO CONFIGURE FTP FOR THE SAP ABAP SYSTEM.

• Check FTP server IP and network Port.
  • Note down the FTP IP and port provided by FTP/OS team.
  • Telnet FTP server IP on a specific port. The default port is 21.
  • Telnet Syntax (Linux & windows): telnet <IP> <PORT>
• Check FTP is accessible from SAP system OS.
  • telnet 123.12.21.20 21

• • Make sure it will connect.

• Add FTP server entry in SAP Table.
  • Maintain FTP entry in SAP table (SAPFTP_SERVERS_V) using tcode sm30
  • SAPFTP_SERVER_V is a client dependent table. Add entry in those specific clients who are going to connect to FTP.

• • Click on the Maintain button & click on the New Entries button.

• • Add IP address, PORT and Description.

• • After maintaining entry click on the save button.

• Test FTP connection using SAP standard Program.
  • Execute SAP program rsftp002 using tcode SA38.

• • Click on the execute button and enter details.

• • I am using RFC “SAPFTPA” as FTP is only accessible from the SAP server.

• • If the connection is not successful you get the error like below.

• • or like below.

• • If the connection is successful you will get the output like below.

All screenshots are captured by me.

• The above procedure will also work for the ABAP systems.
• Telnet is a very useful tool to check the service port and its accessibility from the target.
  • Check on this link for more details about Telnet information
• SAPFTP_SERVERS_V Table is used to store the information about the allowed FTP server.
  • Without entry in this table SAP will not able to establish the connection to the FTP server.
  • If maintain * in this table all FTP servers will be accessible.
• FTP server by default runs on port 21, If the port is different so maintain that port in SAP_FTP_SERVER_V.
• Program RSFTP002 is used to test FTP connection and run execute FTP command.

• There are two RFC that we can use to access FTP.
  • SAPFTP uses frontend/Local computer internet to access the FTP server.
  • SAPFTPA uses backend/SAP server internet to access the FTP server.

Thank you !!!
